Mhangura (Cu)
Kana mhangura (Cu) yakanyungudutswa mune aruminiyamu alloys, iyo michina zvivakwa inovandudzwa uye kucheka kuita kunova nani.Nekudaro, iyo corrosion kuramba inodzikira uye kupisa kunopisa kunowanzo kuitika.Mhangura (Cu) setsvina ine mhedzisiro yakafanana.
Iyo simba uye kuoma kweiyo alloy inogona kuwedzerwa zvakanyanya nemhangura (Cu) inodarika 1.25%.Nekudaro, kunaya kweAl-Cu kunokonzeresa kuderera panguva yekufa, kuchiteverwa nekuwedzera, izvo zvinoita kuti saizi yekukanda isagadzikane.
Magnesium (Mg)
Iyo shoma shoma ye magnesium (Mg) inowedzerwa kudzvinyirira intergranular corrosion.Kana iyo magnesium (Mg) yemukati ikadarika kukosha kwakatarwa, fluidity inodzikira, uye brittleness yekupisa uye simba rekuita zvinodzikiswa.
Silicon (Si)
Silicon (Si) ndiyo inonyanya kukosha yekuvandudza fluidity.Iyo yakanyanya fluidity inogona kuwanikwa kubva eutectic kusvika hypereutectic.Nekudaro, iyo silicon (Si) iyo inopenya inoita kuti igadzire mapoinzi akaomarara, zvichiita kuti kucheka kuita kuwedzere.Naizvozvo, kazhinji hazvibvumidzwe kudarika eutectic point.Pamusoro pezvo, silicon (Si) inogona kuvandudza kusimba kwesimba, kuoma, kucheka kuita, uye simba pakupisa kwakanyanya uku ichideredza kureba.
Magnesium (Mg) Aluminium-magnesium alloy ine yakanyanya kunaka corrosion resistance.Naizvozvo, ADC5 neADC6 maaloyi asingadyi ngura.Kusimba kwayo kwakakura kwazvo, saka ine inopisa brittleness, uye makanda anowanzo kuputika, zvichiita kuti kukanda kunetse.Magnesium (Mg) sekusachena muAl-Cu-Si zvinhu, Mg2Si ichaita kuti kukanda kuve brittle, saka chiyero chinowanzo kuve mukati me0.3%.
Iron (Fe) Kunyange zvazvo iron (Fe) inogona kuwedzera zvakanyanya kutonhora kwe recrystallization ye zinc (Zn) uye inonotsa kugadzirwa kwekristalllization, mukufa-casting kunyunguduka, iron (Fe) inobva kune iron crucibles, gooseneck tubes, uye maturusi ekunyunguduka, uye inonyungudika mu zinc (Zn).Simbi (Fe) inotakurwa nealuminium (Al) idiki zvakanyanya, uye kana simbi (Fe) ikadarika muganho wekunyungudika, inopenya seFeAl3.Kukanganisa kunokonzerwa neFe kunowanzo gadzira slag uye kuyangarara seFeAl3 makomisheni.Iko kukanda kunova brittle, uye machinability inoderera.Kuyerera kwesimbi kunokanganisa kutsvedzerera kwenzvimbo yekukanda.
Kusachena kwesimbi (Fe) kuchagadzira tsono-sekristaro yeFeAl3.Sezvo kufa-kukanda kuchikurumidza kutonhora, makristasi anonaya akanyanya kunaka uye haagone kutorwa sezvinhu zvinokuvadza.Kana zvirimo zviri pasi pe0.7%, hazvisi nyore kudhiza, saka iyo iron ye0.8-1.0% iri nani yekufa-casting.Kana pane simbi yakawanda (Fe), masimbi esimbi achaumbwa, achigadzira pfungwa dzakaoma.Uyezve, kana iyo iron (Fe) yemukati inodarika 1.2%, inoderedza kuyerera kweiyo alloy, kukuvadza kunaka kwekukanda, uye kupfupisa hupenyu hwezvikamu zvesimbi mumidziyo yekukanda kufa.
Nickel (Ni) Kufanana nemhangura (Cu), kune tsika yekuwedzera simba rekusimba uye kuoma, uye ine simba guru pakudzivisa kuora.Dzimwe nguva, nickel (Ni) inowedzerwa kuti ivandudze kusimba kwepamusoro-kupisa uye kupisa kwekudzivirira, asi ine simba rakaipa pakurwisana nekuora uye kupisa kwekushisa.
Manganese (Mn) Inogona kuvandudza kusimba kwepamusoro-kupisa kwema alloys ane mhangura (Cu) uye silicon (Si).Kana ikadarika imwe muganhu, zviri nyore kugadzira Al-Si-Fe-P+o {T*T f; X Mn quaternary compounds, iyo inogona kuumba nyore mapepa akaoma uye kuderedza kupisa kwekushisa.Manganese (Mn) inogona kudzivirira iyo recrystallization process yealuminium alloys, kuwedzera tembiricha yerecrystallization, uye kunyatsonatsa iyo recrystallization zviyo.Kunatsiridzwa kwerecrystallization zviyo kunonyanya kukonzerwa nekukanganisa kweMnAl6 zvidimbu zvakasanganiswa pakukura kwezviyo.Rimwe basa reMnAl6 kunyungudutsa simbi isina kuchena (Fe) kuumba (Fe, Mn) Al6 uye kuderedza zvinokuvadza zvesimbi.Manganese (Mn) chinhu chakakosha chealuminium alloys uye inogona kuwedzerwa seyakamira Al-Mn mabhinari alloy kana pamwe chete nezvimwe zvinosanganisa zvinhu.Naizvozvo, akawanda aruminiyamu alloys ane manganese (Mn).
Zinc (Zn)
Kana isina kuchena zinc (Zn) iripo, icharatidza brittleness yepamusoro-yekushisa.Zvisinei, kana yakabatanidzwa ne mercury (Hg) kuti iite alloys yakasimba yeHgZn2, inobudisa simba guru rekusimbisa.JIS inoti zviri muZinc isina kuchena (Zn) zvinofanirwa kunge zviri pasi pe1.0%, ukuwo zvekunze zvichikwanisa kubvumidza kusvika pa3%.Hurukuro iyi hairevi zinc (Zn) sechikamu chealloy asi kuti basa rayo setsvina inokonzeresa kutsemuka mukukanda.
Chromium (Cr)
Chromium (Cr) inoumba intermetallic compounds yakadai se (CrFe) Al7 uye (CrMn) Al12 mualuminium, ichidzivisa nucleation uye kukura kwekristalllization uye kupa mamwe maitiro ekusimbisa kune alloy.Inogonawo kuvandudza kuoma kwealloy uye kuderedza kushushikana kwekuora kwekupwanya kunzwa.Nekudaro, iyo inogona kuwedzera quenching sensitivity.
Titanium (Ti)
Kunyangwe huwandu hushoma hwetitanium (Ti) mune alloy inogona kuvandudza mashandiro ayo emuchina, asi inogona zvakare kudzikisira yayo magetsi conductivity.Izvo zvakakosha zvirimo zvetitanium (Ti) muAl-Ti akateedzana alloys ekunaya kwemvura kuomesa anenge 0.15%, uye kuvepo kwayo kunogona kuderedzwa nekuwedzera kweboron.
Lead (Pb), Tin (Sn), uye Cadmium (Cd)
Calcium (Ca), lead (Pb), tin (Sn), uye kumwe kusvibiswa kunogona kuvapo mualuminium alloys.Sezvo zvinhu izvi zvine nzvimbo dzakasiyana dzekunyunguduka uye zvimiro, zvinogadzira makomisheni akasiyana nealuminium (Al), zvichikonzera kusiyana kwakasiyana pamidziyo yealuminium alloys.Calcium (Ca) ine yakanyanya kuderera yakasimba solubility mualuminium uye inoumba CaAl4 makomisheni ane aruminiyamu (Al), iyo inogona kuvandudza kucheka mashandiro ealuminium alloys.Lead (Pb) uye tin (Sn) isimbi yakaderera-inonyunguduka ine yakadzika yakasimba solubility mualuminium (Al), iyo inogona kuderedza simba reiyo alloy asi inovandudza kucheka kwayo kuita.
Kuwedzera lead (Pb) yemukati inogona kuderedza kuoma kwe zinc (Zn) uye kuwedzera kunyungudika kwayo.Nekudaro, kana chero yemutobvu (Pb), tin (Sn), kana cadmium (Cd) ichipfuura huwandu hwakatarwa mualuminium: zinc alloy, ngura inogona kuitika.Kuora uku hakuna kuitika, kunoitika mushure meimwe nguva, uye inonyanya kutaurwa pasi pekushisa kwepamusoro-soro, hunyoro hwemhepo.
